5N2 Share Ownership on macos

I’m having a heck of a time with a share on our 5N2. I am unable to change the ownership of files on the share. They seem to be copied with some unknown permissions, and macos isn’t allowing them to change. The share is mounted manually as an AFP share. Is anyone using a 5N2 successfully w/ macos? Thanks.

APF might be the problem. I saw in recent past it was not supported, maybe it is now. It would be good to know as I have a Mac also.

I switched to afp because I thought it would fix it. SMH
